BARREL.

Specification of Letters Patent.

Patented Ju1y 24, 190e;

.ippiiman 218,1 rune 21,1905. serial No. 266,216.

l citizen of the United States, residing at the flange of the city ofNew York, in the State of New York, have invented new and usefulImprovements in Barrels, of which the following is a specification.

My invention relates to metal barrels adapted to contain oils,chemicals, and other liquids requiring absolutely tight joints.

In structures of this character used heretofore the head has beensecured to the shell by means of rivets, brazing, and by both rivets andbrazing. Rivets alone do not make a satisfactory joint, andbrazing-solder affects injuriously some chemicals, which prohibits itsuse for such pu oses. Brazing, moreover, is diiiicult an expensive,especially when ap lied in a circular line to join a head with a s ell.To overcome such disadvantages, barrels have been made wherein a jointbetween the shell and head is formed on a hoop having a recess intowhich the ed` es of the shell and flange of the head are rol ed' andclamed therein around a shoulder of the hoop y means of a flange pressedinto such recess. In such construction,v however, considerable diiicultyhas been found in maintaining the end of the shell and flange of the`head clamped tightly around the shoulder of the ho'o by means of theedge of the oop. In such construction, moreover, when the hoop is bentslightly, as when a barrel with its contents is upended carelessly orthe barrel is ermtted to fall heavily on one point of the oop, the edgeof the ange is drawn away from the shoulder of the hoop, and the shelland flange of theA head become loosened slightlyat such point and causethe barrel to leak. In such a case it is practically impossible to bringthe hoop back ,jto its original shape and re-form the joint.

My invention has for its object to secure the head to the shell or' abarrel by means of a tight joint formed without the use of rivets orbrazing and adapted to be maintained in a serviceable condition. This Iaccomplish by the means illustrated in the acompanying drawings, inwhich- Figure 1 is a side elevation of a barrel embodying m invention.Fig.- 2 is a vertical section of t e same.

As illustrated in the drawings, A represents a cylindrical shell havingits ends inclined inward and provided with a circumferential riba,extending outward and ab ruptly from the shell, thereby making'anannular shoulder af, an ular in cross-section with the end of the she l.A head B, having its circular or body portion preferably concavo-convexin cross-section, is provided with a cylindrical iange inclined inwardand ada ted to bear against the inner end of the she A. A rib b,corresponding with the rib a'of the end of the shell, is formed in thelan e of the head, extendin outward from the an e of the head abru t soas to form an annu ar shoulder b angu ar in cross-section on one side ofthe flange and a corresponding annular recess on the o posite side. Theshoulder a of the end ci) thel shell is compressed and embedded soclosely into theaunular recess of the flange of the head as to make anabsolutely tight joint between such parts, through which even oils andchemicals cannot leak. The outwardly-extendin portions of theinterlockin ribs of the she l and head are, moreover, (Irawn so tightlytogether as to revent any leakage between such parts. his isaccomplished by first forming the rib in the end of the shell andpressing the rib into the flan e of the head, so as to en age the rib ofthe s ell.

A head-and C is applied to the end of the shell and lange -of the headto protect such arts and take the strain from the end of the barrel.This band has an inclined wall bearing against the iiange of the headwith its lower portion extending referably to the circular ortion of thehea and the band is provide with a flange c, which is turned over ontothe outer extremity of the shell, with its ed e referably bearin againstthe rib of the s ell), so as to clamp ihe shoulders of the head andshell and bind them tightly together. By means of such construction atight joint between the end of the shell and flange of the head ismaintained even when the outer edge of the head-band nas become IOO bentslightly, for the reason that the joint is the shoulders of the shell tobecome loose and start a leak, the angular shoulders of the shell andhead-band ma be re-formed and the vjoint restablished y bending thesurplus metal forming the ribs over toward the edge of the flangeof thehead-band and the leak stop ed without re-i'orming or rebending the hea-band itself.

The shapeof the ribs may be modified.

y thereby in the end of the shelland flange of the head.

What I 'claim as new, and desire-to secure by Letters Patent, is-

Ina barrel, the combination with a shell, having its end inclinedinward, of'ahead hav-- ing an inclined flange,- and a head-band havin aninclined Wall bearing against the lange of the head and'provide with aflange adapted to clamp the edges of the shell and ange of the head, theshell and flange ofthe head being provided With interlocking ribs andannular angular shoulders compressed tightly together and formedindependently zo ROBERT W. HARDIE.
